Product Summary
The LM2903N Low-power dual voltage comparator consists of two independent lowpower voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The LM2903N also has a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.
Parametrics
LM2903N absolute maximum ratings: (1)VCC, Supply voltage: ±18 to 36 V; (2)Vid, Differential input voltage: ±36 V; (3)Vin, Input voltage: -0.3 to +36 V; (4)Tj, Maximum junction temperature: +150℃; (5)Tstg, Storage temperature range: -65 to +150℃.
Features
LM2903N features: (1)Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V; (2)Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at +5 V); (3)Low input bias current: 25 nA typ.; (4)Low input offset current: ±5 nA typ.; (5)Input common-mode voltage range includes negative rail; (6)Low output saturation voltage: 250 mV typ. (IO = 4 mA); (7)Differential input voltage range equal to the supply voltage; (8)TTL, DTL, ECL, MOS, CMOS compatible outputs.
